Server crash

[Ultimabrines]

Hello, my server crashes every 50-60min, its very weird. I have disabled and remove skripts and plugins but with no succes. 
[12:41:56 INFO]: CasvdPol issued server command: /plugins [12:41:59 INFO]: CasvdPol issued server command: /pumpkins [12:42:02 INFO]: CasvdPol issued server command: /pumpkins 10 [12:42:07 INFO]: CasvdPol issued server command: //undo [12:42:08 INFO]: CasvdPol issued server command: //undo [12:42:09 INFO]: CasvdPol issued server command: //naturalize [12:42:18 INFO]: CasvdPol issued server command: //naturalize [12:42:26 INFO]: CasvdPol issued server command: //asc [12:42:28 INFO]: CasvdPol issued server command: //asc 1 [12:42:30 INFO]: CasvdPol issued server command: //asc 1 [12:42:33 INFO]: CasvdPol issued server command: //asc 1 [12:42:39 INFO]: CasvdPol issued server command: //asc 10 [12:42:44 INFO]: CasvdPol issued server command: //air [12:42:48 INFO]: CasvdPol issued server command: //undo [12:42:51 INFO]: CasvdPol issued server command: /up 2 [12:42:54 INFO]: CasvdPol issued server command: /up 24

these were the last commands I did, as you can see they are not that big that they should crash a server. 
 

and this is the msg i got:

If your server just randomly crashes and logs just cut off and don't provide any errors fill out a support ticket here: https://minehut.com/support/form
